A series of 3-(3,5-di-tert-butyl-4-hydroxybenzylidene)pyrrolidin-2-ones was synthesized and evaluated as candidate antiinflammatory/analgesic agents as well as dual inhibitors of prostaglandin and leukotriene synthesis. Some compounds that showed dual inhibitory activity were found to possess equipotent antiinflammatory activities to indomethacin, with reduced
